in this screen shot shows where your mod needs to go and how to set up mod folder
the next screen shot shows my folder set up for my map pack
the stagiing area is located for windows users located local disk C program files x86,steam,user data "user id,game folder id,446800,local"

under Linux the staging_area folder in

$HOME/.steam/steam/userdata/$USERID/446800/local/staging_area/
$USERID means the large individual numbered folder just mentioned above ;)

in this screen shot i am showing how your mod lua file need to have in itmod lua file steam where to put the file on the workshop you can use note pad to create your mod lua file i recomend note pad it is simple to use and can create Lua files when you go to save your file your file name needs to be Mod.lua and your file option set to all files. atfer you have saved your mod lua file as a lua file remove the.lua from the name as it is not needed after saving
you can take the mod.lua file from downloaded files and edit it to tell steam where to put your mod

staging_area
- myname_mymod_1
- - mod.lua, and workshop preview.jpeg
- - res
- - - the rest of the files
in the res folder your mod needs to be in its respective game folder in my case it is the maps folder but for someone else it could be different for example a model file would need to be in the model folder
For maps the setup is
staging_area
- myname_mymod_1
- - mod.lua,and workshop preview.jpeg
- - maps
- - - your map files

start the game and look for the publish mod button
click it and you get this screen
click on your mod
check your file details and then hit the publish button Time it takes depends on you upload speed and file size once the upload is complete the steam overlay will open to the workshop page of your item. The final thing to is make your file viewable to everyone that is the job done and your first file uploaded to the workshop.
